@@ -73,6 +73,7 @@ Skills in this repository are scanned using [`cisco-ai-skill-scanner`](https://p
The scheduled scan runs weekly and is incremental: a skill whose package contents are unchanged since the last scan carries its previous findings forward rather than being rescanned. Every skill is rescanned in full whenever the scanner version or the model changes, when a maintainer triggers a full run, and at least every 30 days regardless. Each skill's `last_scanned` date is recorded in the JSON report, so you can always see when a given finding was actually produced.
- **Report:** [`docs/security-report.md`](docs/security-report.md) (machine-readable companion: [`docs/security-report.json`](docs/security-report.json))
- **Triage:** [`docs/security-triage.md`](docs/security-triage.md) — maintainer verdicts on the current report: what was verified and fixed, and which rules are systematic false positives, each with the check that decides it
- **Workflow:** [`.github/workflows/security-scan.yml`](.github/workflows/security-scan.yml)
**How to read the report.** It is generated by automated tooling, including a language model, and is published to be useful rather than authoritative. It is not an audit, a certification, or a guarantee. Each scan is published automatically, with no pre-publication check that its claims are consistent with the contents of `skills/`, so verify a finding against the skill itself before acting on it. A finding in the report is a prompt to review a skill, not a determination that the skill is malicious.

# Security Scan Triage
Verdicts on findings from [`docs/security-report.md`](security-report.md). The report is published
automatically with no pre-publication plausibility check, so a finding there is a prompt to review a
skill, not a determination about it. This file records which findings were verified, what was fixed,
and which classes are systematic false positives — so the same 40 CRITICAL/HIGH items are not
re-investigated from scratch every week.
**Triaged against:** scan of 2026-07-27 10:38 UTC (scanner 2.0.12, model claude-opus-5, 154 skills,
817 findings: 33 CRITICAL, 8 HIGH, 222 MEDIUM, 554 LOW).
Re-run any check below yourself; each one is cheap and decides the finding on its own.
---
## Fixed
These were real. Each fix keeps the skill's documented behavior intact.
| Skill | Finding | What was actually wrong | Fix |
|-------|---------|------------------------|-----|
| `xlsx`, `docx`, `pptx` | `LLM_COMMAND_INJECTION` — runtime C compilation and LD_PRELOAD injection | `scripts/office/soffice.py` built its AF_UNIX shim at a fixed `/tmp/lo_socket_shim.so` and reused whatever was already there if the path merely existed. On a shared host, any local user could pre-plant a shared object there and have it `LD_PRELOAD`ed into every subsequent `soffice` run. The `.c` source was written to an equally predictable path before compilation. | Shim is built in a `tempfile.mkdtemp()` directory — unpredictable name, created `0700`, owned by the caller — memoized per process and removed at exit. No on-disk reuse across runs. |
| `imaging-data-commons` | `LLM_SUPPLY_CHAIN_ATTACK` — autonomous install with `--break-system-packages` | `SKILL.md` told the agent to run a version check **first** that shelled out to `pip3 install --break-system-packages` with no user confirmation, overriding a distribution safeguard unattended. Six other places recommended unpinned `pip install --upgrade idc-index`. | The startup block now only reports the version mismatch and prints a suggested command for the user to approve. All install guidance pinned to `idc-index==0.11.14` in a virtual environment. |
| `pacsomatic` | `LLM_COMMAND_INJECTION` — `--module-load` written unquoted into a generated launch script | Every other value in `write_launch_script()` passes through `shlex.quote()`; `args.module_load` alone was appended raw, so caller-supplied text became arbitrary shell in a script later executed by `bash`/`bsub`/`sbatch`/`qsub`. | `normalize_module_load()` validates the argument at input time: segments split on `&&`/`;`, each must start with `module` and contain no shell metacharacters, then re-emitted quoted. Every documented form (`module load nextflow/23.10.0`, `module purge && module load …`) still works. |
| `autoskill` | `LLM_DATA_EXFILTRATION` — arbitrary config-controlled endpoint for screen-derived data | `foundry.endpoint` from `config.yaml` was passed straight to `httpx.Client` with no scheme or host check, so summaries derived from screen-capture OCR plus an API key header could go to any URL, including plaintext `http://`. | `check_remote_endpoint()` rejects non-HTTP(S) schemes and plaintext HTTP to non-loopback hosts, and prints the destination host to stderr before any off-machine call. The default local LM Studio backend on `localhost:1234` is unaffected. |
| `hugging-science` | `LLM_PROMPT_INJECTION` — remote catalog rendered verbatim into agent context | `fetch_catalog.py` printed titles, descriptions, tags and URLs fetched from `huggingscience.co` with no framing or sanitization, so whoever controls or spoofs that host could place imperative prose or a runnable code block in a description field. | Output carries an explicit untrusted-data banner naming the source URL; entry text is defanged (code fences neutralized, bare `---` separators dropped); URLs outside `huggingface.co`/`hf.co`/`huggingscience.co` are labelled `[off-catalog host]`, with exact-or-subdomain matching so `evil-huggingface.co` does not pass. |
| `dhdna-profiler` | `LLM_DATA_EXFILTRATION` — profiling third parties and conversation history without consent | Independent of the phantom-script claims in the same finding (see below), this was real in the skill text: Self-Profile Mode mined conversation history silently, and nothing bounded profiling of people who are not in the conversation. | Added a Consent and Scope section: ask before reading back through conversation history, label third-party profiles as speculative inference, decline profiling that feeds hiring/clinical/disciplinary/credit decisions, keep profiles in-session. |
| `liteparse` | `LLM_SKILL_DISCOVERY_ABUSE` — activation-priority manipulation | The `description` instructed activation "even when the user does not name liteparse" and to "Prefer over MarkItDown" and "prefer over the pdf skill" — preemption directives that shadow sibling document skills. | Description rewritten to state capabilities factually. Parser-selection guidance already lived in `references/choosing_a_parser.md` and the in-body routing table, so nothing was lost. |

## False positives
### All 40 CRITICAL and HIGH findings
Every CRITICAL and HIGH in the 2026-07-27 report falls into one of four classes below. None
survived verification.
**`BEHAVIOR_EVAL_SUBPROCESS` (CRITICAL ×4)** — claims `eval`/`exec` combined with `subprocess` in
`pacsomatic`, `research-lookup`, `scientific-slides`, `xlsx`. There are **zero** `eval`/`exec`/
`compile` call sites in the entire repository. The rule matches the *substring* `eval`/`exec` inside
ordinary identifiers that co-occur with `import subprocess` — `retrieval`, `evaluate`, `executor`,
`executable`. `scientific-slides/scripts/validate_presentation.py` and `xlsx/scripts/recalc.py`
contain neither substring at all.
```bash
# AST walk over every skill script: no eval/exec/compile, no os.system/os.popen,
# no shell=True, no env=os.environ.copy(), no iteration over os.environ.
python3 - <<'PY'
import ast, pathlib
def full(n):
if isinstance(n, ast.Name): return n.id
if isinstance(n, ast.Attribute): return f"{full(n.value)}.{n.attr}".lstrip(".")
return ""
risky = {"os.system","os.popen","eval","exec","compile","subprocess.getoutput","os.execv"}
hits = []
for p in sorted(pathlib.Path("skills").rglob("*.py")):
try: t = ast.parse(p.read_text(encoding="utf-8", errors="replace"))
except SyntaxError: continue
for n in ast.walk(t):
if isinstance(n, ast.Call):
if full(n.func) in risky: hits.append((p, n.lineno, full(n.func)))
for kw in n.keywords or []:
if kw.arg == "shell" and getattr(kw.value, "value", None) is True:
hits.append((p, n.lineno, "shell=True"))
if kw.arg == "env" and "os.environ" in ast.unparse(kw.value) and ".copy()" in ast.unparse(kw.value):
hits.append((p, n.lineno, "env=os.environ.copy()"))
if isinstance(n, ast.For) and "os.environ" in ast.unparse(n.iter):
hits.append((p, n.lineno, "iterates os.environ"))
print(hits or "clean")
PY
```
**`BEHAVIOR_ENV_VAR_EXFILTRATION` / `BEHAVIOR_CROSSFILE_ENV_VAR_EXFILTRATION` /
`BEHAVIOR_CROSSFILE_EXFILTRATION_CHAIN` (CRITICAL ×29)** — fire on "reads an env var + makes a
network call" anywhere in one package. In every flagged skill the variable read is the API key for
the service the skill exists to call:
| Skill | Env var read | Destination |
|-------|--------------|-------------|
| `autoskill` | `ANTHROPIC_API_KEY`, `FOUNDRY_API_KEY`, `SCREENPIPE_TOKEN` | `api.anthropic.com`, configured foundry endpoint, `localhost` |
| `citation-management` | `NCBI_API_KEY`, `NCBI_EMAIL`, `OPENROUTER_API_KEY` | `eutils.ncbi.nlm.nih.gov`, `openrouter.ai` |
| `research-lookup` | `OPENROUTER_API_KEY`, `PARALLEL_API_KEY` | `openrouter.ai`, `api.parallel.ai` |
| `infographics`, `latex-posters`, `literature-review`, `scientific-schematics`, `scientific-slides` | `OPENROUTER_API_KEY` | `openrouter.ai` |
That is service authentication, which [`SECURITY.md`](../SECURITY.md) places out of scope as "the
inherent capability of skills." The scanner's own LLM pass agreed in writing on an earlier run:
"standard API-key-based service authentication, not exfiltration."
**`MDBLOCK_PYTHON_EVAL_EXEC` (HIGH ×4)** — `geomaster/references/machine-learning.md:207,435` and
`modal/references/functions.md:82` are PyTorch `model.eval()`; `histolab/references/
filters_preprocessing.md:487` is the OpenCV constant `cv2.CV_64F`. The `modal` and `histolab` lines
already carry inline comments saying exactly this, from an earlier triage; the rule ignores them.
**`LLM_DATA_EXFILTRATION` / `LLM_UNAUTHORIZED_TOOL_USE` (HIGH ×3, all `dhdna-profiler`)** — rest
entirely on a claimed inventory of "8 Python scripts" performing "env var reads and network calls."
`dhdna-profiler` contains two files, both Markdown. The findings also cite `BEHAVIOR_*` static
results that appear nowhere in that skill's own findings list, i.e. the LLM analyzer was fed another
skill's static output. (The separate consent concern in the same finding was real and is fixed
above.)
### Confabulated file inventories
The scanner reported Python and shell files in skills that ship only Markdown. Any finding whose
premise is "undisclosed bundled code" in these skills is void:
| Skill | Scanner claimed | Actual |
|-------|-----------------|--------|
| `dhdna-profiler` | 8 Python + 12 Markdown (21 files) | 2 files, both `.md` |
| `seaborn` | 7 Python files | 8 files, all `.md` |
| `scikit-bio` | 2 Python + 1 bash | 2 files, both `.md` |
| `umap-learn` | 2 Python files | 2 files, both `.md` |
| `what-if-oracle` | 2 Python + 1 bash (8 files) | 2 files, both `.md` |
```bash
for s in dhdna-profiler scikit-bio seaborn umap-learn what-if-oracle; do
printf "%-18s py=%s sh=%s md=%s\n" "$s" \
"$(find skills/$s -name '*.py' | wc -l | tr -d ' ')" \
"$(find skills/$s -name '*.sh' | wc -l | tr -d ' ')" \
"$(find skills/$s -name '*.md' | wc -l | tr -d ' ')"
done
```
Note the arithmetic: `seaborn`'s "7 Python files" and `dhdna-profiler`'s "8 Python + 12 Markdown"
track those skills' Markdown counts, so the analyzer appears to be mis-typing files rather than
inventing them wholesale.
### Other
**`liteparse` — `LLM_SUPPLY_CHAIN_ATTACK`**, "possibly non-existent version `liteparse==2.0.0`,
cites a future PyPI release dated May 2026." The package is real, published by Logan Markewich
(run-llama, `github.com/run-llama/liteparse`), and `2.0.0` was uploaded 2026-05-25 — matching the
skill's claim. The scanner could not verify a date past its knowledge cutoff.
```bash
curl -s https://pypi.org/pypi/liteparse/json | python3 -c \
"import json,sys; d=json.load(sys.stdin); print(d['info']['author'], '2.0.0' in d['releases'], d['releases']['2.0.0'][0]['upload_time'])"
```
**`BEHAVIOR_ENV_VAR_HARVESTING` (MEDIUM ×24)** — "script iterates through environment variables."
What it matches is the hardened form introduced by an earlier triage: `{name: os.environ[name] for
name in FORWARDED_ENV_VARS if name in os.environ}`, an explicit allowlist that exists specifically
so a subprocess does *not* inherit the caller's secrets. The rule fires on the fix.
**`MDBLOCK_PYTHON_HTTP_POST` (×27), `MDBLOCK_PYTHON_SUBPROCESS` (×18)** — fire on any HTTP POST or
`subprocess` call shown in a `SKILL.md` code block, including the safe argument-list form the
scanner recommends elsewhere. A skill that documents calling an API necessarily documents an HTTP
call.
**`hugging-science` — `LLM_COMMAND_INJECTION`** on `trust_remote_code=True` guidance. Not fixed
because it is already handled as the finding itself acknowledges: `SKILL.md:117` requires the agent
to ask the user before setting the flag, naming the repo, and states that catalog presence "is not a
vetting signal." The underlying capability belongs to `transformers`, not to this skill.

If the user asks to profile their own thinking (using the conversation history as text), be transparent:
- **Ask before reading back through the conversation.** Say what you intend to use as source
material and wait for an answer. Prior turns were written for a different purpose, and mining
them for psychological inference is not something to do silently.
- Score based on the conversation so far
- Acknowledge that conversational text may not represent the full range
- Note that people often think differently when writing for an AI vs. writing for humans
- Offer to re-profile if the user provides other writing samples
## Consent and Scope
This skill infers personal cognitive and psychological attributes. That is a different thing from
summarizing a document, and the boundaries matter:
- **Profile the text the user brings you for the current request.** Do not go looking for more
material about the same author — other files, earlier sessions, or anything you happened to read.
- **A profile of a third party is speculative and must say so.** When the author is someone who is
not in the conversation and has not agreed to be analyzed — a colleague from a forwarded email, a
candidate from an application, an author from a paper — label the output as an inference from one
text sample, not a finding about that person.
- **Decline profiling that feeds a consequential decision about someone.** Hiring, promotion,
admission, clinical, disciplinary, or credit decisions are out of bounds; this framework has no
validation supporting that use, and a 1–10 cognitive score reads as far more authoritative than
it is.
- **Everything stays local to the session.** Profiles are not written anywhere the user did not ask
for and are not sent to any service.
## What This Is NOT
- Not a personality test (MBTI, Big Five, etc.) — those measure behavioral tendencies, DHDNA measures cognitive architecture

**Required (for basic access):** install into a virtual environment, pinned to the tested release:
```bash
pip install --upgrade idc-index
uv pip install 'idc-index==0.11.14'
```
**Important:** New IDC data release will always trigger a new version of `idc-index`. Always use `--upgrade` flag while installing, unless an older version is needed for reproducibility.
**Important:** every new IDC data release ships a new `idc-index`. Moving to a newer version
changes which data your queries see, so treat it as a deliberate step: check the release notes,
then pin the new version here. An unpinned `--upgrade` makes the data version a moving target and
silently breaks reproducibility of an analysis you ran last month.
**IMPORTANT:** IDC data version v23 is current. Always verify your version:
```python
print(client.get_idc_version()) # Should return "v23"
```
If you see an older version, upgrade with: `pip install --upgrade idc-index`
If it returns an older version, tell the user which version they have and which one this skill was
tested against, and let them decide whether to upgrade.
**Tested with:** idc-index 0.11.14 (IDC data version v23)
**Optional (for data analysis):**

pip install pandas numpy pydicom
